so far completed pip by pip...
Here is the definition from Scott Carney:
Bat Pattern Elements:
• B point at a less than a 0.618 retracement of XA, preferably a distinct 50% or
38.2% retracement.
• BC projection must be at least 1.618.
• AB=CD pattern is usually extended.
• 0.886 XA retracement.
• C point with range between 0.382 and 0.886.
